A woman in preterm labor at 30 weeks of gestation receives two 12 mg doses of betamethasone (Celestane) intramuscularly. The purpose of this pharmacologic treatment is to:

The question that the nurse would prioritize the least during the assessment is "Do you plan to have a vaginal or cesarean delivery?" This is because the priority at this point is to determine the urgency of the situation and assess the patient's current condition. The patient's delivery plan can be addressed later after the initial assessment is completed and the patient's stability has been established.

The other questions are all important in determining the cause and severity of the bleeding and the appropriate course of action. The question about the number of weeks is important to determine the gestational age and potential causes of bleeding, as some causes are more common in certain stages of pregnancy. The question about pain can help to determine the possible causes of bleeding and the patient's comfort level. The question about the last ultrasound is important to determine the location of the placenta and whether there are any abnormalities or potential complications.

In the case of a bioterrorism attack involving anthrax, the main priority for the nurse is to administer antibiotics within 48 hours of exposure using the Strategic National Stockpile. Anthrax is a serious bacterial infection that can be used as a bioterrorism weapon. Antibiotics, such as ciprofloxacin, doxycycline, and penicillin, can be used to prevent anthrax from developing in people who have been exposed.

There is currently no vaccine available for anthrax exposure. Also, symptom support alone is not enough in cases of anthrax exposure, as anthrax can progress rapidly and lead to serious complications. Placing everyone who was exposed in quarantine may not be necessary in all situations, and should be determined on a case-by-case basis depending on the extent and severity of the exposure.
